On the Tracks

After the successful completion of our race cars we're now on to building our ramp/track.  The first length is built so the next task is the construction of an automatic car release mechanism — so there's no cheating!! ;)

The mantra for preparing wires for soldering… "Strip, Twist and Tin"

New Year, New Energy

Our Stereo Amplifier project is back on the table after the Christmas hiatus.  It's all finishing up now.  We've got to be careful we don't rush it now though because we don't want to spoil all the good work that has been done so far.

We had a blast!

What an amazing time we all had last week with Adrian and James from Atec Engineering! 

Some technical issues on the computer-based drawings lead to a last minute decision being made to cut our projects on a laser cutter rather than the water-jet.  It was a slower process but it got the job done.

Everyone was amazed that light — just light — could cut through wood and plastic!  We found that we needed to make 2-3 passes to cut all the way through — it's only a 50W laser — but it certainly did the job.  The cut is around a tenth of a millimeter across so incredibly accurate!

Most of the projects were cut in 3.6mm plywood.  Two were cut in plastic — one in opaque black and one in clear.  They'll look amazing when put together.

Hard at work on our speaker enclosures.  Everyone was wowed by the demonstration of how much difference a well designed enclosure can make to the quality of sound coming from our little speakers.  Bass Ports for all!
